feat(kpi): ADR-090-D MASTER §7.1 北極星 KPI 5 斷鏈全修
2026-04-18 晚（台北時區）— ogt + Claude Opus 4.7 (1M)
MASTER §7.1 15 個北極星 KPI 實測對標發現 5 個斷鏈:
#3 fine-tune JSONL /week — finetune_exports 表不存在
#4 MCP 呼叫/24h — timeline_events 沒 mcp_call event_type
#6 Declarative 修復使用率 — remediation_events 表不存在
#7 general 兜底 17.3% — classify_alert_early 漏 5 類
#10 notification_outcomes /week — 表不存在
本 commit 全修。
## 1. Migration: adr090d_kpi_data_sources.sql (3 張表)
- finetune_exports — P3 Fine-tune JSONL 追蹤
- remediation_events — P5 Declarative 修復追蹤
- notification_outcomes — 通知品質 + RLHF 語料
Idempotent (CREATE TABLE IF NOT EXISTS), 已 apply 進 prod。
## 2. classify_alert_early 擴 4 類規則 (降 general 兜底)
- test 攔截: Test*/FPTest/FingerprintTest/ADR089*Test/L4Closure*/*FreshUniq*
→ category='test', TYPE-1 純通知
- High*CPU/Memory/Disk/Load → host_resource
- TLS*/SSL*/*ProbeFailure* → ssl_cert
- PostgreSQL*/MySQL*/MongoDB*/*DiskGrowthRate → database
預期 general 17.3% → 3-5% (達標 <10%)。
## 3. finetune_exporter DB 寫入
_run_export() 結尾寫 finetune_exports 一筆,含 checksum/size/record_count。
## 4. declarative_remediation DB 寫入
evaluate() 後 fire-and-forget _log_remediation_event() 寫 remediation_events
(status='pending', remediation_type 依 tier 自動判為 declarative/imperative/gitops_pr)。
## 5. telegram_gateway DB 寫入 (send_approval_card)
_send_request 成功返回 message_id 後寫 notification_outcomes 一筆,
channel='telegram', delivery_status='delivered|failed'。未來人類按鈕時
update user_action → RLHF 訓料黃金。
## 6. pre_decision_investigator MCP 呼叫追蹤
_call_single_tool() finally 寫 timeline_events event_type='mcp_call',
含 provider/tool/status/duration_ms/error。24h 內 MCP 呼叫可 SQL 量測。
## 預期量化改善
| KPI | 修前 | 修後 24h 後應見 |
|-----|------|----------------|
| #3 fine-tune /week | 0 (表不存在) | >=10 (每週 cron 跑) |
| #4 MCP 呼叫/24h | 0 | >0 (實測將寫 timeline) |
| #6 declarative 使用率 | 表不存在 | 有資料 (pending/success/failed 分佈) |
| #7 general 兜底 | 17.3% | <10% |
| #10 notification_outcomes | 0 | 每次 approval card 寫一筆 |
